不幸的是，当我键入：

你需要python开发库来构建python模块：
sudo apt install python3-dev libpython3-dev
应该为你照顾。
但是在Ubuntu中添加它的推荐方法是使用Ubuntu存储库。 因此，要为python3安装mysql绑定，请运行
sudo apt install python3-mysqldb
这将安装从Python 3连接到mysql所需的绑定，并确保它将与系统的其他包一起升级。 建议这样做，除非您特别需要更新的版本，或者Ubuntu存储库中没有该软件包。
MySQLdb不能与Python 3一起工作。如果可能你从MySQLdb切换，那么我建议你使用MySQL连接器Python 。 因为它适用于Python 2和3，它是MySQL的官方Oracle驱动程序，用于处理Python。
pip install mysql-connector-python
如果pip失败，您可以从https://dev.mysql.com/downloads/connector/python/下载安装程序
即使用DEB软件包安装MySQL Connector 请参阅本指南以下载和安装
此模块遵循Python数据库API规范v2.0（PEP 249）。
然后使用mysql连接器python的connect()方法连接MySQL.pass所需的参数为connect（）方法。 即主机，用户名，密码和数据库名称
